Extrahepatic portal venous obstruction. A retrospective analysis
Summary
Extrahepatic portal venous obstruction frequently causes portal hypertension in children, often presenting with gastro-intestinal bleeding. Management focuses on conservative care and hemorrhage control, as surgery is generally not recommended.
Area of Science:
- Pediatric Gastroenterology
- Vascular Surgery
- Hepatology
Background:
- Extrahepatic portal venous obstruction (EHPVO) is a common cause of pediatric portal hypertension.
- Clinical presentation often includes gastro-intestinal hemorrhage or incidental splenomegaly.
- Normal liver function is a key diagnostic indicator.
Purpose of the Study:
- To review the diagnosis and management of extrahepatic portal venous obstruction in children.
- To emphasize conservative management strategies for portal hypertension secondary to EHPVO.
- To provide guidance on the surgical and non-surgical treatment of this condition.
Main Methods:
- Diagnostic criteria for EHPVO including esophageal varices and normal liver function.
- Confirmation via portal venography.
- Review of management approaches, including conservative care and surgical interventions.
Main Results:
- Diagnosis is suggested by esophageal varices in patients with normal liver function.
- Portal venography confirms the obstruction.
- Conservative management with intensive hemorrhage control is advised.
- Surgical shunts do not consistently reduce hemorrhage frequency.
- Splenectomy is contraindicated.
Conclusions:
- Extrahepatic portal venous obstruction requires a conservative management approach focusing on hemorrhage control.
- Surgical interventions like shunts and splenectomy are generally not beneficial and potentially harmful.
- Early diagnosis and appropriate management are crucial for pediatric patients with EHPVO.
